The A5700 high-precision MEMS heading and attitude reference system (AHRS) is a highly reliable and cost-effective six-axis MEMS inertial system for heading and attitude measurement, widely applicable in navigation, control, and measurement applications such as satellites, vehicles, ships, and drones. The A5700 series integration a high-performance MEMS gyroscope and MEMS accelerometer within a single integrated structure, with comprehensive compensation for temperature-dependent parameter zero points, scale factors, non-orthogonal errors, and acceleration-related terms, ensuring sustained high measurement accuracy. The system outputs attitude information through navigation calculations based on the angular motion of the three-axis MEMS gyroscope sensor and the linear acceleration measured by the three-axis MEMS accelerometer sensor.

Application Scenarios
A série A5500 é um sensor IMU/VRU/AHRS composto por uma IMU MEMS de alto desempenho, um magnetômetro e um giroscópio de eixo único aprimorado. Equipado com filtro de Kalman estendido adaptativo desenvolvido internamente, algoritmo de análise dinâmica de ruído da IMU e algoritmo de análise do estado de movimento do sensor, o sensor garante a precisão do ângulo de atitude em condições de alta dinâmica e reduz a deriva do ângulo de direção. Cada sensor passa por uma compensação precisa, incluindo temperatura, viés de zero, fator de escala e eixo transversal, antes de sair da fábrica.
